Mystery tree with large 5-lobed leaves
I may have done something really stupid - left something growing in the newest flower bed just in case it was a cool plant that piggy-backed in with a nursery flower. But this plant went from 5-inches tall to 5-feet tall in just a few months. It has long, pointed, deeply-lobed, alternate leaves.
Photos are posted on my blog if anyone has any ideas.
Thanks in advance,
Annie at the Transplantable Rose
